I have a Pioneer stove with a power vent. The manometer shows a reading of 3. I have several co detectors with the one closest to the stove being a digital type with the alarm set to go off at 30 ppm. The reading on the unit shows 11 ppm. Is there cause for concern? I'm vented properly and with a 100 year old house it's drafty.Thanking you in advance

The SOP for my dept is we have to go on SCBA with any detectable levels over 10PPM. SO, If I would not be allowed in your home breathing your air. Just to look around, I don't think I will be living there.

Shut it down ...Ventilate the house...Clean out the vent pipes and power venter...Check for leaks after the power venter...If you still have any CO readings after that...Shut down and call an expert...It ain't worth the risk...

I have my stove in the basement, I do not have any co detector in a close prox to the stove. The manual actually recommends not too I believ for the same reason that was previously posted, having the door open for a small amount of time. I do have 3 meters located in various points in my house. One in living space, one in hallway by my daughters room and one by my cellar steps which is open(nice big air return) I have had a big fat 0 on my meters since a fired up. I wouldnt let anything go unchecked with any reading other than 0.

Good to hear...Too many sad stories in MA after the big snow...In one, they actually had a working CO but it looks like they disassembled the detector... Was on the bed with a good battery next to it...The fire marshal reassembled it and it was fully functional... End result...Two people and two dogs dead...

Just a note, the OSHA Personal Exposure Limit for CO is 50 PPM average exposure over a 8 hr day. Removal of person from source if over 100 PPM. A small amount of CO is not immediately deadly, but a concern. CO builds up in the bloodstream over time as the blood cell have a greater infinity for CO than Oxygen.

Don't the readings for ppm on the detector stand per hour ? I can start a snowblower, lawn tracter then take it outside, in a ranch style garage and have a 25 ppm reading in the basement, with the basement door kept closed, except to go threw it
